Editing

Delete Channels

Reference

Menu:

Channel ‣ Delete Channels

Shortcut:

Delete, X

Removes the selected channels from the current action.

Warning

Make sure the mouse cursor is hovering over the channel region before using the keyboard shortcuts. If it’s hovering over the main region, you’ll only delete the selected keyframes, not the full channels.

Un/Group Channels

Reference

Menu:

Channel ‣ Un/Group Channels

Shortcut:

Ctrl-Alt-G, Ctrl-G

Un/Groups the selected channels into a collection that can be renamed by double-clicking its name. Grouping channels helps keep the view more organized.

Toggle/Enable/Disable Channel Settings

Reference

Menu:

Channel ‣ Toggle/Enable/Disable Channel Settings

Shortcut:

Shift-W, Shift-Ctrl-W, Alt-W

Toggles, enables, or disables a certain setting for the selected channels:

Protect

When a channel is protected (closed padlock icon), it can’t be edited. Instead of pressing Shift-W and selecting Toggle, you can also simply press Tab.

Mute

When a channel is muted (empty checkbox), it doesn’t affect the animation.

Toggle Channel Editability

Reference

Menu:

Channel ‣ Toggle Channel Editability

Shortcut:

Tab

Locks or unlocks a channel for editing.

Extrapolation Mode

Reference

Menu:

Channel ‣ Extrapolation Mode

Shortcut:

Shift-E

Changes how the curve behaves before its first keyframe and after its last keyframe.

Constant:

Constant extrapolation.

Continue in a straight line, keeping the same value as the first/last keyframe. This is the default.

Linear:

Linear extrapolation.

Continue in a straight line, keeping the same slope as on the first/last keyframe.

Make Cyclic:

Repeat the whole curve. This works by adding a Cycles modifier.

Clear Cyclic:

Remove the above modifier, making the curve non-repeating again.

Add F-Curve Modifier

Reference

Menu:

Channel ‣ Add F-Curve Modifier

Shortcut:

Shift-Ctrl-M

Shows a submenu from where you can add a modifier to the active curve. Settings for these modifiers can be found in Sidebar ‣ Modifiers.

Show/Hide

Hide Selected Curves H

Hides the selected curves.

Hide Unselected Shift-H

Hides all curves except the selected ones.

Reveal Curves Alt-H

Shows all previous hidden curves.

Expand/Collapse Channels

Reference

Menu:

Channel ‣ Expand/Collapse Channels

Shortcut:

NumpadPlus, NumpadMinus

Expands or collapses the selected headers.

Move

Reference

Menu:

Channel ‣ Move…

Lets you reorder the selected channels in the list:

• To the top Shift-PageUp

• Up one line PageUp

• Down one line PageDown

• To the bottom Shift-PageDown

Revive Disabled F-Curves

Reference

Menu:

Channel ‣ Revive Disabled F-Curves

Clears the “disabled” tag from all F-Curves to get broken F-Curves working again. (A curve is broken if it references a property that doesn’t exist.)

Keys to Samples

Reference

Menu:

Channel ‣ Keys to Samples

Shortcut:

Alt-C

Switches the selected curves from interpolating between a set of keyframes to using a sampled value at each full frame. This is a destructive process that removes the ability to edit the curve. It’s mainly used to reduce the file size with large datasets, as samples take up less space than keyframes.

Between samples (on subframes), the curve interpolates linearly.

Samples to Keys

Reference

Menu:

Channel ‣ Samples to Keys

Switches the selected curves from using samples to using keyframes, making them editable. Note that this creates a keyframe on every frame.

Sound to Samples

Reference

Menu:

Channel ‣ Sound to Samples

Creates a sampled curve based on a sound file. Use Samples to Keys if you need to edit it.

Lowest Frequency

Cutoff frequency of a high-pass filter that is applied to the audio data.

Highest Frequency

Cutoff frequency of a low-pass filter that is applied to the audio data.

Attack Time

Value for the hull curve calculation that tells how fast the hull curve can rise. The lower the value, the steeper it can rise.

Release Time

Value for the hull curve calculation that tells how fast the hull curve can fall. The lower the value, the steeper it can fall.

Threshold

Minimum amplitude value needed to influence the hull curve.

Accumulate

Only the positive differences of the hull curve amplitudes are summarized to produce the output.

Additive

The amplitudes of the hull curve are summarized. If Accumulate is enabled, both positive and negative differences are accumulated.

Square

Gives the output as a square curve. Negative values always result in -1, and positive ones in 1.

Square Threshold

All values lower than this threshold result in 0.

Bake Channels

Reference

Menu:

Channel ‣ Bake Channels

Generates new keyframes for the selected curves.

Frame Range

The range that will be baked. Defaults to the scene range or preview range.

Frame Step

Distance between keyframes. Can be used to create a keyframe every 10 frames or even every half frame.

Remove Outside Range

Removes existing keys outside the specified baking range.

Interpolation Type

The interpolation type for the new keys.

Bake Modifiers

If enabled, the new keyframes are based on the modified curve, and the modifiers get deleted.

If disabled, the new keyframes are based on the original curve, and the modifiers stay applied.

Discontinuity (Euler) Filter

Reference

Menu:

Channel ‣ Discontinuity (Euler) Filter

Cleans up Euler rotation channels that suffer from Gimbal Lock. The channels of all three euler rotation axes need to be selected for this to work.

Frame Selected Channels

Reference

Menu:

Channel ‣ Frame Selected Channels

Shortcut:

NumpadPeriod

Pans and zooms the view to show all keyframes of the selected curves. You can also click a channel with Alt-MMB.
